Title: High-power single-mode strained single quantum well InGaAs/AlGaAs lasers grown by molecular beam epitaxy on nonplanar substrates

Abstract

Strained single quantum well InGaAs/AlGaAs graded-index separate confinement heterostructure lasers have been grown by molecular beam epitaxy over nonplanar substrates. In addition to the low threshold currents provided {ital in} {ital situ} by lateral current blocking {ital pn} junctions obtained by plane-dependent doping of the amphoteric Si dopant, we observe variations in lasing wavelength, efficiency, and internal absorption as a function of the central (100) facet length. These variations are associated with increased indium composition in the strained quantum well which arises from incorporation of adatoms migrating from the low-growth (311){ital A} side facets to the preferential growth (100) active area facets. Uncoated devices (750 {mu}m{times}4 {mu}m) have been found to have threshold currents as low as 6 mA ({ital J}{sub th}=320 A/cm{sup 2}) and exhibit single-mode behavior to greater than 100 mW at a wavelength of {similar to}1.0 {mu}m when reflectivity modified (90%/10%).
